Thumb and pushwheel switches are electronic switches that are activated by rotating a thumbwheel or pushing a button. They are commonly used in a variety of applications, such as industrial control systems, consumer electronics, and medical devices.

Thumbwheel switches typically consist of a housing, a thumbwheel, and a set of electrical contacts. When the thumbwheel is rotated, it completes a circuit between the contacts, allowing electrical current to flow through the switch.

Pushwheel switches, also known as incremental encoders, are similar to thumbwheel switches, but they use a rotary knob or button to rotate a wheel that is marked with incremental markings or detents. This provides tactile feedback and allows for precise control over the position of a mechanical component or the selection of options in a menu.

Thumb and pushwheel switches offer several advantages over other types of switches. They provide a simple and intuitive means of controlling circuits or selecting options, and they offer tactile feedback that can help to ensure reliable operation. They are also highly durable and can withstand frequent use and harsh environments.
